phalconphp 访问触发事件的控制器名称

Question

如何从事件本身引用触发 beforeExecuteRoute 的 controllerName 和 actionName？

<?php
use Phalcon\Events\Manager as EventsManager;

//Create a events manager
$eventManager = new EventsManager();

//Listen all the application events
$eventManager->attach('micro', function($event, $app) {

    if ($event->getType() == 'beforeExecuteRoute') {
        //how to get controller name to handle acl stuff
    }
});

Answer 1

来自文档 - http://docs.phalconphp.com/en/latest/api/Phalcon_Mvc_Dispatcher.html

getModuleName () - Gets the module where the controller class is
getControllerName () - Gets last dispatched controller name
getActionName () - Gets the lastest dispatched action name

例子：

<?php
use Phalcon\Events\Manager as EventsManager;

//Create a events manager
$eventManager = new EventsManager();

//Listen all the application events
$eventManager->attach('micro', function($event, $app) { 
    if ($event->getType() == 'beforeExecuteRoute') {            
        $controllerName = $app->getControllerName();
        $moduleName = $app->getModuleName();
        $actionName = $app->getActionName();          
    }
});

这样你就可以得到字符串格式的路由来解析它：

$router->getMatchedRoute()->getPattern();

希望对您有所帮助。我发现没有其他方法可以做到这一点。

如果您没有调度程序，您必须从路由器获取这些值。我对微应用的细节不是很熟悉，但是看文档应该是这样的。

<?php
use Phalcon\Events\Manager as EventsManager;

//Create a events manager
$eventManager = new EventsManager();

//Listen all the application events
$eventManager->attach('micro', function($event, $app) {

    if ($event->getType() == 'beforeExecuteRoute') {
        //how to get controller name to handle acl stuff

        DI::getDefault()->get('router')->getControllerName();
        DI::getDefault()->get('router')->getActionName();

        // or

        $app->getRouter()->getControllerName();
        $app->getRouter()->getActionName();
    }
});

这行得通吗？

我实际上遇到了类似的困惑，但是其他答案没有帮助，并且 Phalcon 的官方文档没有找到正确的方法，所以如果您使用的是 Micro，很难找到有效的答案在网上。所以我之前用自己的反思来了解Phalcon的，最后得出以下答案，希望对你有所帮助。祝你好运！

<?php

$eventsManager = new \Phalcon\Events\Manager();
$eventsManager->attach(
    'micro:beforeExecuteRoute',
    function (\Phalcon\Events\Event $event, $app) {
        $controllerName = $event->getSource()->getActiveHandler()[0]->getDefinition();
        $actionName = $event->getSource()->getActiveHandler()[1];
    }
);

$app = new \Phalcon\Mvc\Micro($di);
$app->setEventsManager($eventsManager);

如果你想用 before 事件实现 ACL，下面的 AclAnnotation 代码可能会有所帮助：

<?php

class AclAnnotation
{
    protected $private = true;
    protected $roles = [];
    protected $component = [];
    protected $access = [];

    public function __construct($event, $app)
    {
        $controllerName = $event->getSource()->getActiveHandler()[0]->getDefinition();
        $actionName = $event->getSource()->getActiveHandler()[1];

        $reflector   = $app->annotations->get($controllerName);
        $annotations = $reflector->getClassAnnotations();
        if (!$annotations) {
            throw new ErrorException('The permission configuration is abnormal. Please check the resource permission comments.');
            return;
        }

        if (
            $annotations->has('Private')
            && ($annotation = $annotations->get('Private'))->numberArguments() > 0
        ) {
            $this->private = $annotation->getArguments('Private')[0];
        }

        if (
            $annotations->has('Roles')
            && ($annotation = $annotations->get('Roles'))->numberArguments() > 0
        ) {
            $this->roles = $annotation->getArguments('Roles');
        }

        if (
            $annotations->has('Components')
            && ($annotation = $annotations->get('Components'))->numberArguments() > 0
        ) {
            $this->components = $annotation->getArguments('Components');
        }

        $annotations = $app->annotations->getMethod($controllerName, $actionName);
        if (
            $annotations->has('Access')
            && ($annotation = $annotations->get('Access'))->numberArguments() > 0
        ) {
            $this->access = $annotation->getArguments('Access');
        }
    }

    public function isPrivate()
    {
        return $this->private;
    }

    public function getRoles()
    {
        return $this->roles;
    }

    public function getComponents()
    {
        return $this->components;
    }

    public function getAccess()
    {
        return $this->access;
    }
}

在 index.php 中创建事件监听器：

<?php

    $eventsManager = new \Phalcon\Events\Manager();
    $eventsManager->attach(
        'micro:beforeExecuteRoute',
        function (\Phalcon\Events\Event $event, $app) {
            $aclAnnotation = new AclAnnotation($event, $app);
            if (!$aclAnnotation->isPrivate()) {
                return true;
            }

            $acl = $app->currentACL;
            // Verify that you have access permission for the interface
            if (!$acl->isAllowed($aclAnnotation->getRoles(), $aclAnnotation->getComponents(), $aclAnnotation->getAccess())) {
                throw new \ErrorException('You do not have access to the resource', 40001);
                return false;
            }

            return true;
        }
    );

    $app = new \Phalcon\Mvc\Micro($di);
    $app->setEventsManager($eventsManager);
